Arthur Poitout@arthur-poitout.bsky.social · 2w ago🌱 Summer reading? Here's our recent @pnas.org ! doi.org/10.1073/pnas... We reveal how plasma membrane nanodomains generate localized H₂O₂ nanoenvironments during osmotic stress. The ROP6-RBOH-PIP2;7 module creates a feedforward loop that amplifies ROS signaling. #PlantBiology #CellBiology #ROS
@babliadhikary.bsky.social, Higashi et al. show that PAK4 drives dynamic vertex remodeling in cells and embryos through spatiotemporal regulation of #myosin II. Inhibition of PAK4 disrupts tissue packing and compromises junctional continuity and barrier function. rupress.org/jcb/article/...

Anja Geitmann@geitmannlab.bsky.social · 2w agoWhy do primary plant tissues hold their shape? We are told it's because of turgor pressure—but how does that work mechanically? We investigated how pressurized cylindrical structures support themselves. Read here: doi.org/10.1039/d6sm... Funded by @hfspo.bsky.social www.plantbiomechanics.net
📢 Two postdoc positions available in @mc-caillaud.bsky.social's group (RDP lab, ENS de Lyon), part of an ERC Consolidator. Project: how plant cells orient their division, combining cell biology, molecular genetics, and mechanical modelling. 📅 Deadline: 1 Oct 26 | Start: Nov 26 onwards Details 🧵👇

Charlotte Kirchhelle@ckirchhelle.bsky.social · 3mo agoIncredibly proud of this paper showing how plants couple vesicle delivery and phragmoplast expansion during division. This project started in the lab of the great and late Ian Moore, and it was a joy to finish it with @liamelliottplants.bsky.social et al! link.springer.com/article/10.1...
The AlphaFold 3 code is now relicensed from CC BY-NC-SA 4.0 to Apache 2.0 (Commercial use, Distribution, Modification, ...) 🎉 github.com/google-deepm...
Release AlphaFold v3.0.3 · google-deepmind/alphafold3
Version 3.0.3 changes the AlphaFold 3 code license from CC BY-NC-SA 4.0 to Apache 2.0. Moreover, it provides bug fixes and a performance improvement for large inputs. We thank everyone who reported...
